- Do not use open flames near the workplace, do not smoke or hold any objects that are very hot. There is a danger of an accident! Keep a fire extinguisher ready;
- Keep the workplace well ventilated. Fuel fumes are poisonous;
- The fuel system is under pressure. When the system is opened, fuel can escape under pressure. Collect the fuel with a rag. Use safety glasses;
- Take special precautions when working on diesel engine power system components. This is especially true for injectors. Keep in mind that the fuel pressure at the outlet of the injectors is about 1100 atmospheres. Do not expose any part of the body to the jet of fuel;
- Hose connections are fastened with tape or clamp clamps. Clamp clamps must always be replaced with band clamps or clamps of the latest design. For the installation of band clamps there is a special device, for example HAZET 796-5;
- Thoroughly clean the connections and the places adjacent to them before opening;
- Place the removed parts on a clean lining and close. Use polyethylene or paper for this. Do not use fluffy rags for this;
- Carefully close open parts or put technological plugs if the repair will last for some time;
- Replace only clean parts. Remove spare parts from the packaging only immediately before installation. Do not use parts that have been stored unpackaged (e.g. stored in a toolbox);
- With an open fuel system, if possible, do not work with compressed air. If possible, do not move the car;
- Do not use sealants containing silicone. The silicone elements in the engine that got into the engine do not burn out and damage the oxygen sensor.
Safety measures when removing the fuel tank:
- Before removing the tank, drain the fuel from it or pump out the fuel with a pump specially designed for this purpose;
- The fuel tank is removed from the underside of the vehicle. Before disconnecting the tank mounting clamps, bring a jack and linings to it from below;
- An empty tank is explosive and cannot be disposed of in this form. Before disposal, the tank must be cut into pieces. Be careful not to create a spark. To do this, hand over the fuel tank to a specialized company;
- After installing the tank in place, start the engine and check the tightness of all connections.
